PURPOSE: A linear vibration motor is provided to maintain intrinsic elastic properties of an elastic component by preventing the driving region of an elastic component from being welded to a stator part. CONSTITUTION: A stator part includes a magnetic force part. A vibrator part includes a coil facing the magnetic force part and generating electromagnetic force, and a printed circuit board. An elastic component(200) includes an upper part, a lower part, and multiple bending parts(230), and elastically supports the linear vibration motion of the vibrator part. The upper part of the elastic component is combined with the inner upper side of the stator part by welding. The multiple bending parts connect the upper part and the lower part, and generate elastic force. The upper part of the elastic component is formed with multiple welding parts and multiple piercing parts(220) surrounding the outer circumferential surfaces of the multiple welding parts. |
